Alkaloid content variations in lupin (<i>Lupinus</i> L.) genotypes and vegetation periods

Abstract

Testing for alkaloids in lupine varieties was conducted at the Vokė Branch of Lithuanian Institute of Agriculture during a competitive trial of feeding lupine (Lupinus L.) in 2006-2007. Samples were taken from feeding yellow lupine (Lupinus luteus L.), 'Trakiai' and 'Vilčiai' varieties, the narrow-leaved lupine (Lupinus angustifolius L.), 'Vilniai' variety and from cropper No. 1702. Alkaloid content was estimated in the periods of bud formation, full blossom, shining legumes and full maturity. The test material included exsiccates of leaves, stems, inflorescences, legumes, and seeds.According to the results, in the 'Trakiai' and 'Vilčiai' varieties of forage yellow lupins (Lupinus luteus L.) total alkaloids were lower than in the 'Vilniai' variety of narrow-leaved lupins (Lupinus angustifolius L.) and variety N1702.The highest content of alkaloids was identified in the periods of full blossom and legumes. A lower content was noted during bud formation, and the lowest in the full maturity period.High levels of alkaloids are present in legumes, while stems, inflorescences and leaves contain lesser amounts. The lowest content of alkaloids was identified in seeds.

Preliminary estimation of forage yield and feeding value of Lupinus angustifolius varieties cultivated in Jalisco, México, during the cool season

“…Differences in the alkaloid content in seeds of L. angustifolius varieties are well known (Jansen et al, 2012;Jansen et al, 2015); however, information is limited about the variations in alkaloid content in Lupinus angustifolius varieties used as forage. In Vilniai and N1702 L. angustifolius varieties harvested at four phenological growth stages, Maknickienë and Asakavièiûtë (2008) reported a variation in alkaloid levels from 0.043 to 0.095% and from 0.099 to 0.108%, respectively. These differences in alkaloid content were greater than those found in this study at two harvest dates.…”

“…The alkaloid content in all six varieties did not differ statistically, but values ranged from 0.0022% in Boruta to 0.0046% in Probor, which is considered a very low alkaloid level. According to Maknickienë and Asakavièiûtë (2008), low alkaloid levels in fodder lupines vary within 0.025-0.99%. Differences in the alkaloid content in seeds of L. angustifolius varieties are well known (Jansen et al, 2012;Jansen et al, 2015); however, information is limited about the variations in alkaloid content in Lupinus angustifolius varieties used as forage.…”

Influence of plant growth regulators on indirect shoot organogenesis and secondary metabolite production in Aconitum violaceum Jacq.

“…Although the bioactive alkaloid, that is, aconitine, responsible for therapies, are mainly accumulated in the roots of aconitum plant, alkaloid content were also found in the vegetative parts for example, leaves and so on and constantly changes throughout the growth period (Maknickiene 2008;Sinam and Devi, 2011). In the present study, the secondary metabolite analysis has been done in the vegetative part to know the effect of different types and concentration of PGRs.…”
